I recommend Country Florist at Siglap Center, I brought a photo of what I wanted and the lady gave me suggestions about the bouquet with respect to my dress and settings. Importantly, I find the prices very reasonable too!
Not sure whether you gals have tried elite flora before. The shop is at Chijmes. I used their service. Look for Sam. His design are unique and lovely. Price maybe bit steep, but if you put importance on the decor of the ballroom, what the heck. Once in a lifetime rite?
My florist for ROM was Secret Garden. They are rather pricey but you can trust them to do a good job. Our guests commended much on the floral decor. I worked with Jane. Personally, I feel that she is quite calculative but I have to say that she is
If I'm not wrong, Secret Garden also sponsored Quan Yi Feng's wedding at One Degree 15 recently. And that was so beautifully dreamy.
